Maybe someone could help if there was a little more information. Was any written information provided about the presence of cancer in any of the cores? (To me, pending might mean that additional study of the slides is necessary before a definitive reading can be provided. Your doctor would know the answer...)

Probably waiting for results from pathology lab? it is sent out and hopefully to the few experts that exist in this field (Bostwick, Epstein, Oppenheimer etc.) they are the ones whom review 1st pathologies to confirm or correct what might be found by the average Pathologist. It does make a huge difference, upon reviews things like this have been found: Gleason 6 turns out to be Gleason 8, or Gleason 7 turns out to be non-cancerous altogether and similar stories, or different variants of PCa are found (there a different types, some of these are rare like 1-5% of all cases, but some are way worse than the norm we see with andemo-carcenoma which is the 'norm' present type).

Next get wise and get a copy of the pathology report in your hands, doc has to give you one on request atleast in the USA(he could charge $$ for it-pay it). Needed for second opinions and for forums and discussions by other whom basically know enough about what it says and you will eventually learn the terminology, why? Because you are motivated, it is your journey, you walk the walk, nobody else.

Realize the biopsy is the needle in a haystack concept, gland is the size of a walnut+, so it is possible to miss a region where it could be. Some people get rebiopsied after months go by and monitoring there psa numbers etc.

Do not let pathology words like perineural invasion scare you, basically means PCa was found near blood vessels or a path to go to such, not a plus but is often enough found in pathology, not a rare event. Does not necessarily mean PCa went through you body, it is more possible, and is actually unknown. No scanning method to date is 100% in finding PCa, you need about 1-billion cells grouped for possible detection, clear scans is not a guarantee of no PCa(evidence found often and by other patients histories), it is always good to hear as maybe it is all clear, once detected it is like yeap enough is there to show up so it could also be in other places once outside the gland. (unfortunately the truth)

You should get to know some pathology as to: gleason scores found (could have mulitple scores within the gland), percentages found in each regional/biopsy, how is it scored (3+4)=7 or (4+3)=7 Gleason, the first number indicates which level of cancer was found in higher percentage, the lower your first number and overall number the better off are your chances for cures or survival time (generally speaking).
